How do we know it’s working?

Measuring eye length, and catching myopia early.

  1. 01Myopia control: slowing how fast the eye grows
  2. 02Why does the eye keep growing?

  6. 06How do we know it’s working?

We measure eye length, not just glasses strength

Part 06 · 01
Illustrative growth chart: before treatment the eye crosses centiles; on treatment the curve flattens.

  1. 01

    Precise optical measurement every 6 months

    Accurate to a few hundredths of a millimetre.

  2. 02

    Plotted on growth charts, like height

    We compare your child with children the same age.

  3. 03

    Success = the curve flattens

    Near-normal growth, or even slight shortening early on.

Catching myopia before it starts

Part 06 · 02
Gauge and chart: a reserve of +0.75 D or less around age 6 signals high risk; the window to act is early.
Fig 6.2Hyperopic reserve
  1. 01

    Most young children are slightly long-sighted

    This ‘reserve’ protects against myopia.

  2. 02

    A low or fast-falling reserve is a warning

    +0.75 or less around age 6 predicts future myopia.

  3. 03

    Acting early can delay or prevent it

    More time outdoors, and treatment for high-risk children.

In summary

Part 06
  1. 01Eye length is measured precisely every 6 months.
  2. 02A flattening growth curve means treatment is working.
  3. 03Watching the hyperopic reserve can catch myopia before it starts.
